CLEANER FOB ENGINE-CYLINDERS.

b all whom it may com-em:

it known that I, GEORGE W. GARDNER, a citizen of the United States oi America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cleaners for Engine-Cylinders, of which the following is a specification.

This invention relates to improvements for gasolene gasor other hydrocarbon or elastic fluid. engines, and it consists in certain peculiarities ot' the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The invention has for its principal object to provide automatic, simple and inexpen sive means for cleaning or maintaining in a clean condition the cylinder or cylinders of the engine, which means shall be of such construction, arrangement and relation of its parts to the engine as to utilize the pres-' sure and impulsive force'of the exhaust or escaping gases to create a strong suction from the engine cylinder or cylinders, whereby the foul and residual gases or unconsiu'ned particles of carbon will be with drawn therefrom, as well as from the comb'ustion chamber and exhaust cavity, and so that no back pressure in said parts will occur, and the formation of carbon on the walls thereof: will be prevented, to the end that a pure carbureted charge Will he aftorded for each explosion or discharge of the engine.

Another object of the invention is to utilise the impulsive force of the waste gases to mulllc or reduce the noise incident to the expl sion and exhaust of the engine, by means of a rotary undershot wheel or fan.

Other objects of the invention will be disrlosed in the subjoined description and explanntion.

in the serves to illustrate an embodiment of the invenom-1'1 igure 1 is a side view of a porti n ol the exhaust pipe of an engine, showingf a cleaner embodying the invention mounted thereon and illustrating said pipe as being: provided with a mulllcr of the or dinary construction; Fig. 2 is an enlarged plan view partly in section of the cleaner the exhaust pipe on which Specification of Letters Yatent.

it is mounted, and Fig. 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 2, looking, in the direction indicated by the arrows.

Like numerals of reference refer to corresponding parts through the different views of the drawings.

The reference numeral 5, designates a portion of the exhaust pipe of an engine, which pipe may be provided near its free or discharging end with a mother 6, or" the ordinary or any preferred cbnstruction.

The cleaner consists of a tube or pipe section 7, which is adapted at each of its ends to engage a section of the exhaust pipe, as'is clearly shown in the different views of the drawing, and for this purpose each end of the tube 7, is by preference internally screw threaded to engage external-screw threads on the sect-ions 5, of the exhaust pipe, but it is cl'wvious that said tube and sections may be united in other Ways. The tube or pipe section 7, is provided with an enlargement 8, which, by preference, is located on the upper surface of said tube and in conjunc' tion therewith form partof a casing for a rotary fan or wheel, which is designated as a whole by the reference numeral 9, and consists of a hub 10, and a series of vanes or arms 11, extended radially from the hub so that in the rotation of the fan or wheel the lowerinner surface of the tube 7, and the inner surface of the enlargement 8, of the casing. ne of the sides of the tubular member 7, and of the enlargement 8, has secured thereto by means of screws 12, a plate 13, which is provided centrally with an internally screw threaded projection 14, in which is located a set screw 13, the inner end of which is pointed or cone-shaped as at 16, to engage a similarly shaped socket 17, in one end of the hub of the fan or wheel, and said screw may be fixed in the desired position by means of a jam-nut 18, mounted on the outer portion thereof. The opposite side of the tubular member 7, and its enlargement 8, has secured thereto by means of screws 12, the flattened end or plate 24, of a by-pass tube or pipe 19, the other end of whichis secured to the member 7, and in communication therewith between the enlargement 8, and that end ofas will be" i (it:-
